Iidabashi Naika Shika Kurinikku

Iidabashi Naika Shika Kurinikku sits on the 5th floor of Iidabashi Square Building in Shinjuku, covering both internal medicine and dental under one roof — which is genuinely convenient if you need to sort multiple health issues without clinic-hopping across Tokyo. The internal medicine side handles the usual: checkups, chronic condition management, colds, fatigue, and general adult health concerns.

English capability here is murky. The clinic has some English-facing content on its website, which suggests they’ve thought about international patients, but whether that translates to a smooth English consultation or just a bilingual homepage is hard to confirm. Come prepared with a translation app, written notes about your symptoms, or a Japanese-speaking friend if your health issue is complicated. Iidabashi station is right there — multiple lines, easy access — so at least getting here is painless. Good for straightforward visits; less ideal if you need detailed back-and-forth with your doctor in English.
